661709 divided by 43 
We want to figure out the number of times 661709 can be divided by 43.

Moving on to step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 43

Step 2:
43 goes into 66 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 66 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 43

Going ahead to step 3:
231 divided by 43 is 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 215 from 231 to get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 43

Moving on to step 4:
If we divide 167 by 43, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 153.0
If we subtract 129 from 167, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 43

Going ahead to step 5:
380 divided by 43 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
If we subtract 344 from 380, we get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 43

Moving on to step 6:
If we divide 369 by 43, we get 8 and a remainder of 25.
The next digit of our result is 8. 
Result so far: 15388.0
Deduct 344 from 369 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 43, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15388.5
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 43 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 15388.58
If we subtract 344 from 350, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 43 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 15388.581
The remainder is 17 after subtracting 43 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
170 divided by 43 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 15388.5813
If we take 129 away from 170, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
The number 43 fits into 410 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 15388.58139
If we subtract 387 from 410, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
If we divide 230 by 43, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15388.581395
If we subtract 215 from 230, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
43 goes into 150 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 15388.5813953
Subtracting 129 from 150 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
If we divide 210 by 43, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 15388.58139534
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 15388.58139534, and the remainder is 3.8e-08.
